Suppose a ball is hit at an angle of 60° from point A on the 4.5' by 9' billiards table shown below.Will the ball hit the sides of the table at least five times before going into a pocket? Explain your answer.


Yes. See the sketch. The angle of incidence equals the angle of reflection so that a series of parallelograms is made by the path of the ball.
